Description

The invention relates to an arrangement of a table and a Bildprojizierenden device according to the independent claim 1, the use of such an arrangement in a conference system or video conferencing system according to claim 14 and a method for controlling at least one electrical and / or electronic device by such an arrangement according to the preamble of independent claim 15.

In particular in meeting rooms, it is known to attach image projecting devices, in particular projectors in the area of the ceiling, wherein the projectors image data on a projection surface, which are often formed by a building wall itself or mounted on a wall projection screen.

It is also known in the equipment of conference or video conference rooms that provided on the present in the conference or video conference room table or table arrangement of the table top devices, in particular screens, laptops etc. or embedded in the table touch panels or other control elements are. Such arrangements of devices on tables are visually extremely disturbing because they interrupt the continuity or the planar design of the table top or table surface or dissolve.

Particularly in the case of devices arranged in a vertical position, such as screens, the problem arises in videoconferencing arrangements that the interlocutor connected via the video conference can not recognize the image content displayed on the screen since the display area of the screen can not be detected by the camera of the video conference system. Thus, the connected party can not recognize what is displayed on the screen of his switched party. As a result, there is often uncertainty among the call partners as to whether the connected caller receives the desired picture content.

In addition, the non-visible, standing on the table screens arranged a separating barrier between the interlocutors, since they are arranged wall-like in the receiving area of the camera between the interlocutor and the receiving camera. Thus, such arrangements of screens on the conference table are a hindrance to trusting and successful conference or videoconferencing.

Proceeding from this, it is an object of the invention to provide an arrangement of a table and a bildprojizierenden device that allows for an open and transparent video conferencing, on the other hand, a control of the video conferencing system or other provided in space electronic or electrical units.

The object is achieved on the basis of the preamble of independent claim 1 by its characterizing features. The use of such an arrangement in conference and / or video conference rooms is the subject of patent claim 14. A method for controlling at least one electrical and / or electronic device by an inventive arrangement is the subject of claim 15.

The arrangement according to the invention comprising at least one table with a table top and at least one image projecting device arranged above the table is characterized in that the projection surface is formed by at least a portion of the top of the table top and by the table having at least one touch-sensitive sensor unit the surface of the table top, a touch-sensitive user interface is formed, wherein at least a partial surface of the user interface lies within the projection surface. Due to the arrangement of the invention, it is possible on the table surface, i. to display image data on the top of the tabletop by projection and to make control commands by touch, in particular by touching the finger through the touch-sensitive user interface. As a result, in particular when using such arrangements in conference rooms or video conference rooms in which a large table or several, a table arrangement forming tables are provided and above the seats in each case a bildprojizierende device or groups of seats each a bildprojizierende device is arranged without the use of On the tables standing or protruding from these display units or monitors on the table surface even image data are displayed. As a result, the optical continuity of the table is maintained and it creates an open-acting environment in the conference or video conference rooms, so that a trusting and successful conference or videoconferencing is possible.

In a preferred embodiment, the user interface lies completely within the projection surface. This ensures that can be displayed or projected by the projector on the user interface controls, in particular a control panel with multiple controls. When a user touches the user interface within such a control panel displayed by the projector, such input may be used to control electrical or electronic equipment of the conference room or videoconferencing room.

Further preferably, the user interface forms a portion of the screen, i. the projection surface is made larger than the user interface. As a result, despite displaying, for example, a control panel in the area of the user interface, the further free area of the projection area can be used to display other image contents, for example presentations, etc. Furthermore, it is possible in the area of the user interface, for example, a keyboard or the like can be represented by the projector, so that, for example, a text input via the user interface is possible. In the further area of the projection area, which is not occupied by the user interface, a representation of the inputs can take place, for example, as a text line or the like. Thus, an input comparable to the inputs in tablet PCs is possible by the inventive arrangement. Particularly preferred are a congruent design of the projection surface and the user interface, i. the projection surface and the user interface have the same or substantially the same size and are congruent to each other. In this way, user inputs can be made by the user on the entire projection surface by touching the user interface, as a result of which, as it were, the user interfaces of a tablet PC known from the prior art can be imaged on the table surface.

In a particularly preferred embodiment, the touch-sensitive sensor unit is not recognizable on the upper side integrated in the table top or arranged on the underside of the table top. As a result, the surface of the tabletop is not interrupted even in the area of the touch-sensitive sensor unit and the table appears in the off state of the projector as a conventional table with a continuous, uninterrupted tabletop. Only after the projection of image data onto the projection surface and representation of a control field or control elements does the user recognize that inputs are possible via the arrangement.

In a particularly preferred embodiment, the touch-sensitive sensor unit is provided in a recess of the support material of the table top and is covered by a continuous cover layer. In this case, any cover layers of nonconductive material, in particular veneers, corian, glass, etc., can be used as cover layer. Preferred cover layer materials have a light surface and are matt. As support material solid wood from all common types of wood, real wood fiber boards, plastic plates, Formica plates, plates made of Corian, glass, acrylic glass, natural stone, artificial stone, etc. can be used. The integration of the touch-sensitive sensor unit gives the user again the impression that it is a conventional table, whereby the complete integration in the table also allows the externally protected recording of the touch-sensitive sensor inside the table.

Particularly preferably, the touch-sensitive sensor unit is a capacitive sensor unit. In such capacitive sensor units, a capacitance change is effected by touching the touch-sensitive sensor unit or the touch-sensitive user interface or by approaching the touch-sensitive sensor unit. This change in capacity is localized and evaluated. Depending on the location of the touch or the movement guidance of the touch on the touch-sensitive user interface, a control of the electrical or electronic device or a change in the representation on the projection surface, for example, zoom in or zoom out. Capacitive sensor units are particularly suitable for operation by means of the finger, so that no special input pens or the like are necessary. The touch-sensitive sensor unit may in particular be multi-touch capable, i. be designed for detection and evaluation of multiple simultaneous touches of the touch-sensitive user interface at different locations. As a result, for example, a representation change, in particular a zoom in or a zoom out can be effected. The touch-sensitive sensor unit is a high-resolution unit with a resolution of 4096 × 4096 dots.

Particularly preferably, the touch-sensitive sensor unit is formed from two plate-shaped elements and a sensor layer arranged between these plate-shaped elements. The plate-shaped elements are in this case preferably glass plates, between which the sensor layer is laminated. Such a sensor unit constructed is insensitive and even has sufficient stability, so that it can be easily integrated into the table or placed under this table.

The image-projecting device is particularly preferably a projector, in particular an LED projector. Furthermore, preferably, the projector has an immediate start, ie the image reproduction takes place with high brightness within a few seconds, especially less than five seconds. Furthermore, the projector preferably has an immediate stop, ie a cooling phase is not required and an associated Wiederzündverzögerung does not occur. Projectors with LEDs as light sources or projectors with a LED laser hybrid technology are characterized by a long life of their lamps. For example, they have operating lives ranging from 20,000 to 40,000 hours. They are therefore suitable for continuous use in conference rooms. Furthermore, preferably, projectors that use LEDs as bulbs, a low electrical power consumption. This results in even low heat loss, which can be easily dissipated, even when installing the projector within the ceiling or in lighting modules above the table. In the beam path of the projector, a lens may also be introduced so that depending on the distance of the projector to the surface of the table top a defined projection range in the range between 17 inches and 30 inches screen diagonal, especially 18 inches, 20 inches, 22 inches, 24 Inches, 26 inches, 27 inches, and 28 inches. The brightness of the projector can be between 500 and 3000 lumens, whereby the extremely low projection area on the table for the projectors causes a high brightness of the image, so that a very high visibility of the projection image is ensured even with dark table surfaces.

In a preferred exemplary embodiment, the image-projecting device is integrated in a lighting technology module which is arranged above the table, in particular in the region of the tabletop above the table. As a result, the image data can be imaged on the tabletop via a vertical projection of the light beam downwards. At least one lighting unit for illuminating the table surface and / or at least one document camera and / or at least one motion sensor is preferably provided in the lighting technology module in addition to the at least one image-projecting device. By means of the document camera, for example, image contents can be recorded from the tabletop, for example documents lying on the table, and made available to the other conference participants, in particular also remotely connected conference participants, during a video conference. The motion sensor may be used, for example, to control the projector, to switch the image data displayed by the projector, or the like.

Particularly preferably, the motion sensor is provided above the table, wherein the motion sensor is at least indirectly connected to the image projecting device, that by an output of a movement detection signal from the motion sensor, a connection or disconnection of bildprojizierenden device or a switching of the image displayed by the bildprojizierenden device image data takes place on other image data to be displayed. The motion sensor thus provides an intuitive control device that can be controlled via gesture control, i. by movement of the body or parts of the body of the user, in particular, for example, the arm, can be operated.

In a particularly preferred embodiment, at least partially cover the detection range of the motion sensor and the projection surface. Particularly preferably, the detection range of the motion sensor lies completely within the projection surface. This creates an intuitive system for the user since the exact area occupied by the projector with image data can also be used to control the gesture of the system.

In a particularly preferred embodiment, bildprojizierende devices are arranged such that each between two seats a projection surface is arranged on the surface of the table top over a large table or an arrangement of several tables on which or a large number of seats for conference participants , In this way, two conference participants each can perceive image data imaged by a projector in a part of the surface of the tabletop between them. Thereby, the use of a reduced number of image projecting devices is possible, so that the cost of the entire system can be reduced. Alternatively, all seats can be provided with a bildprojizierenden device.

Particularly preferably, use of the arrangement according to the invention takes place in a conference system or in a video conference system. Here, all seats or groups of seats on a conference table or a conference table arrangement are each equipped with bildprojizierenden above devices so that each seat or group of seats is assigned a projection screen that is well visible from the respective conference participants. The image-projecting devices can be used, for example, to display image data of a presentation on the respective projection surfaces, ie each image-projecting device receives the same image data as the input signal so that each conference participant can directly perceive the presented image contents in front of him / her. This allows for a projection of the presentation data on a central, arranged in space Large projection screen can be dispensed with. Particularly in video conferencing, the arrangement according to the invention offers the decisive advantage that the externally connected opposite party participating in the video conference can at least partially recognize the image data which is imaged by the image-projecting device on the surface of the tabletop so that conventional questions such as "See You the document? "Or" What do you see? "Are no longer necessary. This allows a much more open and trusting video conferencing.

The invention further relates to a method for controlling at least one electrical and / or electronic device by means of an arrangement as described above. The method is characterized in that image data are represented by the image-projecting device on a projection surface formed at least by a partial area of the tabletop, that an input is made to the touch-sensitive user interface through at least one interaction of the user with the touch-sensitive sensor unit Input a control of the electrical and / or electronic device is effected. The arrangement according to the invention can thus not only be used to display image content of a presentation or a video conference, but it can on the touch-sensitive user interface control of electrical or electronic devices, such as computers, a conference or video conferencing system, of devices of the room or the building technology, such as lighting, shading or the air conditioning done.

In a preferred embodiment of the method, at least one control element is displayed on the projection surface. By touching the touch-sensitive user interface in the region of the control element, a signal is generated by the touch-sensitive sensor unit, which signal is evaluated by a control computer and converted into a control signal for an electrical or electronic device. The touch of the control can cause, for example, the increase of the room temperature by the air conditioner or the shutdown of the shading devices.

Particularly preferably, at least one field of control elements is displayed on the projection surface. This field can be used to carry out a large number of control commands or control inputs by the user. Each control is in this case assigned a function, so that control inputs are generated by touching the touch-sensitive sensor unit at the appropriate locations.

In a particularly preferred embodiment, at least partially image data are displayed on the projection surface, which are simultaneously displayed on further image-projecting devices or projected by further image-projecting devices. This is accomplished by coupling the image projecting devices to each other via a video splitter or video router. For example, in a conference room having a table or table arrangement with a seat for a conference leader and multiple seats for a plurality of conference participants, it is possible for the same image data to be projected by the image projecting devices associated with the conference participants, as by the image projecting device associated with the conference leader. The conference leader can, for example, additionally be shown a control panel by the image-projecting device, by means of which he can make inputs to the conference system or videoconferencing system.

In a preferred embodiment, at least one interaction of a user with the touch-sensitive sensor unit or a motion sensor at least partially causes a change of the displayed image data. Thus, for example, in the area of the touch-sensitive user interface, an input facility, for example a keyboard or the like, can be displayed, via which the user can make inputs that directly affect the image contents displayed by the image-projecting device. Furthermore, gesture control can be enabled by a motion sensor, so that switching of the image contents, switching the projector on or off, changes in brightness, etc., are effected, for example, by a fast movement of the hand by the detection area monitored by the motion sensor.

The term "substantially" in the sense of the invention means deviations from respectively exact values by +/- 10%, preferably by +/- 5% and / or deviations in the form of changes which are insignificant for the function.
